This invention relates in general to new and useful improvements in drink mixers, and more specifically to include an attachment for converting drink mixers into mixers for accommodating paper cups and the like.

Drink mixers are primarily constructed whereby a metal cup is used for the mixing of the drink after which the drink is poured from the metal cup into another type of container for drinking. it is, however, more desirable to mix the drink in a disposable container, which container will also be used for holding the drink while being consumed. Attachments have been made for drink mixers whereby the drink mixers may accommodate the paper containers. However, such attachments will accommodate only one size of container. It is therefore the primary object of this invention to provide a cup holder attachment for drink mixers, which cup holder attachment will automatically adjust in height for holding cups of all heights thereby permitting the user of the drink mixer to have a greater range of offerings for the public which permits more competitive merchandising.

Existing drink mixers support the cup in the mixing position both on the bottom flange thereof and on the upper edge thereof. The top cup holder projects down into the cup and during the mixing operation the drink is splashed on the top cup holder with the result that the top cup holders are normally filthy from accumulation of the drink mix. Furthermore, this cup holder cannot be readily cleaned and is thus subject to contamination. Therefore, another object of this invention is to provide a cup holding attachment for drink mixers, which cup holding attachment eliminates the up, or cup holder of existing drink mixers and which is of such a nature whereby it has the dcsired sanitation characteristics.

Another object of this invention is to provide an attachment for a drink mixer, which attachment is of such a nature whereby the cup is covered so as to prevent splashing. This eliminates the need for cautious preliminary manipulation usually necessary to avoid splashing. Furthermore, the hand may be removed from the cup immediately after it is introduced to the [mixture] mixer. This shortens the time needed to mix and serve the drinks.

Another object of this invention is to provide an attachment for drink mixers which is of such a construction whereby it lowers the housekeeping cost and laundry bill by abolishing splattcring and spilling which necessitates constant cleaning of the mixer, adjacent equipment, surrounding tixturcs and windows, as Well as the uniform of the attendants.

Another object of this invention is to provide an improved attachment for drink mixers which attachment is of such a nature whereby it increases the workers capacity because the instant the drink is introduced to the mixer, the operator is free for other duties, and because its use lessens general housekeeping demands both during the daily operation of the mixer and at closing time.

Still another object of this invention is to provide a cup holder attachment for drink mixers, the cup holder attachment being of such a nature whereby loss through spilling and the destruction of paper cups by puncturing Reissued N v. 2f

ice

is completely eliminated, the attachment being so constructed whereby the mixing does not begin until such time as the attachment is fully positioned.

Another object of this invention is to provide an attachment for drink mixers which is so constructed whereby it increases the production capacity because of increased conveniences, the drink mixer being of such a nature whereby each spindle can accommodate a cup of any height whereby the operator may always use the nearest or handicst idle spindle.

Still another object of this invention is to provide an attachment for drink mixers, the attachment being of such a nature whereby space is saved in a large establishment because each drink mixer spindle becomes completely versatile and automatically accommodates cups of all heights eliminating need for a greater number of spindles and mixers.

A further object of this invention is to provide an improved drink mixer attachment, the attachment being of such a nature whereby it reduces the investment necessary for equipment because the attachment makes each mix universal thereby eliminating the requiremen for a large number of mixers of a special purpose type.

A still further object of this invention is to provide an improved attachment for drink mixers, the attachment being of such a nature whereby it makes possible instant effective cleaning of the mixer at any time after the use of mixing a drink with or without removing the attachment by merely placing on the mixer a regular drink mixing cup containing water the action of which cleans all of the exposed portions of the attachment.

Yet another object of this invention is to provide an improved drink mixer attachment which is of such a nature whereby it will create a greater sales appeal in its area of use by presenting to the customers view a drink mixer that at all times is clean in appearance.

These together with other objccts and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Referring now to the drawings in detail. it will be seen there is illustrated in FIGURES 1 and 2 a conventhat tionai type of drink mixer which is referred to in general by the reference numeral 19. The drink mixer 19 includes supporting frame which is referred to in general by the reference numeral 12 and includes a base 14 and an upstanding frame portion 16. The frame portion 16 has secured to the upper end thereof a vertically disposed motor 13 whicit has connected thereto a vertically derending shaft 29. The shaft 20 is provided adjacent the lower end thereof with suitable agitators 22 and 24.

The dr k mixer lil has secured to the base 14 by means of :1 si' e screw 26 a container or cup bottom support 28 which includes a Econtaining] container engaging ledge 30. Carried by the upper part of the frame member 16 is a cup or container guide 32 which is secured in place by means of a fastener 34. Associated with the container guide 32 is miner control mechanism in the form of a switch control lever 36 for controlling the operation of the electric motor 18.

In the normal operation of the standard height containers or cups, the upper portion of the cup is passed behind the guide 32 and engaging the switch control lever 36 so as to move the switch to an on position. Thus. as the container is being positioned relative to the drink mixer 16, the motor 18 is energized and the agitators 22 and 24 are rotated. This occurs before the container or cup is seated on the container support 23. It will thus be seen that initially there is splashing before the container is seated and it is necessary that the operator of the drink mixer 10 have a firm hold on the container otherwise the container is knocked out of the operators hand.

When paper cups are used and the of a standard height. it is necessary ltl be provided with an attachment which will operate the swith ccntrol lever 36 inasmuch as the paper cup will not engage the switch lever 36. One attachment provided to date will accommodate only one height of cup and must be adjusted if the cup height is changed. Another attachment is in the form of an extension collar for the cup which requires a different collar for each different type of cup.

In order to overcome the normal difiiculties encountered in the operation of a drink mixer, there is provided the drink mixer attachment which is the subject of this invcn 't attachment being referred to in general by the r. encc numeral 38. The attachment 38 includes a base which is referred to in general by the reference numeral The base 40 includes a mounting plate 42 which is disposed intermediate the container support 23 and the base 14 and which is held in place by the screw or fastener 25. The mounting plate 42 has extending upwardly therefrom a pair of vertically disposed spaced parallel slcelcs 44 and 46. The guiding sleeves 44 and drink mixer utilizing paper cups are not that the drink mixer t have disposed therein actuating rods 4-8 and 50. respectively, of an actuating mechanism for vertical sliding movement. The upper ends of the rods 48 and 50 are e ted to ether by means of a cross bar 52 which is c h the cup guide 32 so as to pass to the right guide 32-, as viewed in FlGURE 2 and engage 1h lever 36. '.,oscd in the lower ends of the sleeves or tubes 44 fixed pressure coil springs 54. The coil 54 engage the lower ends of the rods 48 and 50 t t3 and 50 upwardly to a position where- 52 will move the switch lever 36 to a po on to move the switch to an on" position. In order that the drink mixer it may remain inoperative except ten it is in use. there is carried by the sleeve 46 a cly releasable latch member 56. The latch momis carried by a pair of mounting brackets 58 which to one side on the sleeve 46 and which has extherehetween a pivot pin 60 on which the latch 5a is pivotally mounted. The latch member 56 a dog portion 62 which is aligned with a slot 6 in the sleeve 45. The dog portion 62 is selectively on able in a notch 65 in the lower part of the rod so as to prevent the upward movement thereof. Thus the upward movement of the rods 48 and 5t) and the cross bar 52 is selectively prevented.

The dog (:2 is so constructed whereby the rods 48 and may be moved downwardly from their elevated positions. Thus the resetting of the latch member 56 will be automatic. The downward movement of the rods 48 and 5h is accomplished by means of an operator 68 which is secured to the upper end of the rod which terminates at the lower end thereof in a hand engaging portion 70.

ifarricd by the rods 48 and S is a cover unit or con- 1 her top engaging means which is referred to in general by the reference numeral 72. The cover unit 72 includes a resilient generally circular mounting clip 74, as is best illustrated in FIGURE 3 which has an entrance opening 76 defined by a pair of flanges 78. The clip 74 is connected by means of spacers St to a pair of sleeves 82 disposed on the rods 48 and 50 for vertical movement.

Renmvably carried by the resilient clip 74 is a cover which may be of any design although a specific cover 84 has been illustrated. The details of the cover 84 will be set forth hereinafter. It is, however, pointed out that the cover thl is of a size to engage over the container which is to be used in conjunction with the drink mixer it). Also, the cover 84 is provided with an opening 86 through which the shaft 2% and the agitators 22 and 24 may pass.

The cover unit 72 is freely carried by the rods 48 and 59 so that the cover unit 72 may be readily moved along the rods 43 and 50. When a cup is removed, the cover unit 72 slides down until the sleeves 82 abut the sleeves 14 and 46.

In the use of the attachment 38 in conjunction with the drink mixer 10, a container, such as the paper cup 83 illustrated in FIGURE 4 is engaged with the underside of the cover 84 and the two moved upwardly until such time as the bottom of the container 88 is aligned with the container seat 28 at which time it is set on the ledge With the container 33 fully seated with repsect to the drink mixer 16 and the cover 34- in place. the latch member 56 is moved to an inoperative position at which time the coil springs 54 urge the rods 43 and 5t] upwardly. The upward movement of the rods 48 and 50 results in the upward movement of the cross bar 52 which in turn engages the switch lever 36 and moves it to an on position. The drink is then mixed within the container 83 a proper length of time without requiring any attendance on the part of the operator of the drink mixer It). At such time as it is deemed that the mixing is completed, the rods 45 and 55} are moved dovi 'rm 'artlly by means of operator hi3 at which time the switch lever 36 will be moved to its oil position and the motor 18 discontinues By moving upwardly on the container slightly so as to disengage from ledge 39 and then moving the container downwardly. the container 88 may be readily removed from the drink mixer 11 Referring now to FTGURES 3 and 4 in particular, it will be seen that there are illustrated the details of the cover 84. The cover 84 includes an outer portion 9%] and an inner portion 92. The outer portion 95) includes a top wall 94 which has depending from the periphery thereof a flange 96. A similar flange 93 is disposed concentric of the flange $6 and inwardly oi the ilange 96. The space between the flanges 96 and $8 will be occupied by the upper edge of the container 88 and thus a seal between the cover 84 and the container 38 is formed.

The central portion 92 includes a top wall 100 which has disposed inwardly of the peripheral edge thereof a depending flange 132. The top wall 94 is provided with an eccentric opening 164 which is defined by a relatively short upstanding flange 1:16. The opening 194 is of a its operation.

size to snugly receive the flange it and thus frictionally mount the central portion 92 within the outer portion 90. Because of the eccentric mounting of the central portion 92 with respect to the outer portion 943, and the eccentric position of the opening 36 in the top wall 160 of the central portion 92, the opening tit: may be positioned as is necessary so as to receive the shaft 23 by rotating the central portion 9?. in the outer portion 90 and rotating the outer portion in the clip 74. Thus the cover 84 permits the attachment 35:5 to be adapted to various types of drink mixers and still receive the shaft the eof.

A modified form of cover is illustrated in FlGURE 12. This cover is referred to in general by the reference numeral 108 and includes an outer portion 119 and an inner portion 112'. The ou er portion 110 differs from the outer portion 90 in that it is of a smaller diameter than the outer portion and does not have an inner flange which corresponds to the flange d8.

Referring now to FIGURE 6 in particular, it will be seen that there is illustrated a modified form of attachment which is referred to in general by the reference numeral 114. The attachment 114 includes a base 116 which is secured to the base 14 of the drink mixer 1% by means of the fastener 26 which also secures the container bottom support 28 to the base 14. The base 116 includes a mounting plate 118 which has extending upwardly therefrom in spaced parallel relation a pair of guide sleeves 12b and 122. Disposed within the upper portions of the sleeves 1.20 and 122 are lower ends of actuating rods 12dand 126, respectively. The upper ends of the rods 124 and 126, like the rods 43 and 50 are connected together by means of a cross bar 128.

Carried by the rods 124 and 126 for vertical sliding movement is a container top engaging cover unit 130 which is substantially identical to the cover unit 72 and differs therefrom only in that a releasable one-way latch 132 has been added.

The latch 132 is carried by that sleeve 82 of the cover unit 130 through which the rod 126 passes. The latch 132 includes a curved lever 134- which is pivotally mounted on a pivot pin 136 carried by a pair of spaced parallel cars 13% which are secured to the sleeve 82 as best seen in FiGURE 7. The lever 13 i is provided with an arcuate slot 149, which slot is best illustrated in FlG- URE 6. Secured to the lever 134 is a first link which is referred to in general by the reference numeral 142. The link 142 includes an upper cross portion 144 and a lower cross portion 146, the cross portions 144 and 146 being connected together by integral. legs 148 which converge downwardly from the upper cross member 144 to the lower cross member 146. The cross member 144 is disposed in the arcuate slot 14%. The cross member 146 is passed through an car of a one-way lock or latch dog 152.

Secured to the opposite side of the sleeve 82, 180 from the centers of the cars 1323, is a vertically elongated mounting plate 154. The mounting plate 154 is provided with a vertically elongated slot 156, as is best shown in FlGURE 6.

The latch 132 also includes a link 158 as seen in FIG- URE 8. The little is formed of an upper cross portion 160, a lower cross portion 162 and a pair of spaced parallel legs 164 formed integral with. the cross portions and 162. The cross portion 156 is disposed in the slot 156 and the cross portion 16?. passes through an ear 166 which extends upwardly from the dog member 152 remote from the car 150.

Referring now to FIGURE 9 in particular, it will be seen that the dog member 152 is generally elliptical in outline and has an elliptical opening 168 through which the rod 126 passes. When the dog member 152 is in the horizontal position, as shown by dotted lines in FIG- URE 6, the latch 132 is free to slide on the rod 126 so that the cover unit 130 may be vertically positioned. On the other hand, when the dog member 152 is disposed at a slight angle to the horizontal, it will grip the rod 126 and be locked thereto. As the latch member 134 is moved upwardly. the dog member 152 will be pulled simultaneously tilted and pulled upwardly. However, because the dog member 152 will immediately grasp the rod 126, and since at this time the cover unit 130 will be resting upon the container 58. this will result in the upward movement of the rods 1234 and 126, as well as the cross bar 128. in this manner the latch 132. when actuated, will operate as lack means for the rods 124 and 126 and cross bar 128. The cross bar 128 will then move the switch lever 36 to an on position.

Disposed in the lower ends of the sleeves 12.0 and 122 are fixed pressure coil springs 170. The coil springs 170 are of such length whereby the cross bar 128 will be supported immediately below the switch lever 36 when the switch is in its off position. Thus after the cover unit 139 has been positioned on the container 38 and the latch member 134 moved upwardly. the rods 124 and 126 need move upwardly only a short distance within the capacity of the latch 132 to move the cross bar 128 to a position whereby it in turn moves the switch lever 36 to an on position.

Referring now to FIGURES l0 and 11 in particular, it will be seen that there is illustrated a modified form of attachment which. is referred to in general by the reference numeral 172. The attachment 172 includes a base 174 which is identical with the base 116. Extending upwardly from the base 174 are actuating rods 176 and 178 which are identical to the rods 124 and 126, respectively, and which are connected together by a cross bar 18%, identical to the cross bar 128.

Carried by the upper portions of the rods 176 and 173 is a cup or container top engaging unit E82 which is identical to the cup unit 72. However, carried by the rods 176 and 178 above the cover unit 1551. are telescoping constant force coil bar springs 184 which engage the upper ends of the sleeve 1% of the cover unit 182. The upper ends of the springs 184 also engage the cross bar 180'.

In the use of the attachment, the cover unit 182 and the rods 176 and 178 are supported by coil springs 188 disposed in the base 174. As the container 88 is being positioned the cover unit 132 is movzd upwardly against the compression of the springs 18%. This results in the upward movement of the rods 176 and 178 and the cross bar 180 so that the cross our 1% lifts the switch lever 36. This, of course, energizcs the electric motor 18. However, the upper end of the container 88 is sealed by the cover unit 182. Further upward movement of the container 8'5 and the cover unit 132 permits the container 88 to be seated on the container support 23. The construction of the springs 184 is such that irrespective of the amount which they are compressed within the compressible range thereof, the force required to compress the springs 18*! remains constant. Thus the cover unit 18?. is held in place on the container 88 under the proper compressing engagement at all times irrespective of variations and heights of the container 88.

From the foregoing. it will be seen that there has been evised several forms of attachments for drink mixers, which attachments are so constructed whereby they may be used to function with paper containers and other types of containers normally used in conjunction with drink mixers and which will seal the drink mixers as is required so as to prevent splashing thus rendering the drink mixer unsanitary.

Further, the attachment firmly holds the container during the mixing operation and requires no attention on the part of the operator. In addition to this, the covers of the various cover units may be readily removed and washed so that the covers may remain sanitary at all times. A further advantage of the present invention is that it may be secured in place by merely removing one fastener, positioning the attachment and then replacing the fastener.

Although only one illustrative form of drink mixer 3115 been shown in the drawings, it is to be understood that the drink mixer attachment is universal in that it may be attached to all types of existing drink mixers. it is to be understood that drink mixers made by diifercnt companies vary in design and/or manner of operation. However, the dilferences of design and/or manner of operation are of such a nature whereby the attachments disclosed herein will readily conform to the variations in design and/or manner of operation and may be interchanged from one manufacturers drink mixer to another. This universal use of the attachment, together with the universal adaptation of the attachment to all types of cups, irrespective of height. makes the attachment readily adaptable to any operation. Furthermore, the fact that the attachment automatically adapts to cups of all heights greatly facilitates the use of the attachment and a drink mixer on which the attachment is mounted.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
